In this modern era, remote control is used to operate electronic device wirelessly from any short distance. By using Tv remote jammer circuit, the remote control of the TV will be stopped. Anyone can prevent other for changing the specific channel of TV. He can watch his favorite channel without any interruption of anyone. Tv remote jammer is an IR jammer which is sending a constant IR pulse with the carrier frequency of the transmitter for confusing the infrared receiver in a TV by producing constant signal. As a result, the receiver will not accept the signal from the remote. Therefore, no action will be taken. It is designed by using IR led, 555 timer IC, capacitor, resistor, potentiometer etc. It is adjusted to produce 38KHz signal. This project is very cost effective and implementation is very easy. Anyone can easily make this circuit for jamming the tv remote in his home. The cost of this project is only 3$-4$. This simple circuit has capability of blocking the communication established between Television and remote of the tv. KeywordsRemote control, TV remote jammer, 555 Timer IC, IR led, Transistor.
